Having used a few different powerbank models over the years – mostly cheap models which barely gave a reliable (nevermind fast!) charge, back in 2014 I decided to upgrade to the best rated powerbank I could find. After lots of research, I decided on the popular 16,750mAh model from RAVPower, which promised to charge an iPhone 6 just over 6 times.

To offer some comparison, those small powerbanks only have a capacity of ~2,000mAh. For perspective, the iPhone 7 has a 1,960mAh battery. So while they look handy, they’re only really suitable as an emergency backup rather than for more regular use.

It served me well and was a great size, however when going to festivals it only just lasted (since I was usually working there from 6-7 days and using my phone a lot). So after seeing the RAVPower 26,800mAh powerbank in Amazon’s Black Friday deals, I decided to upgrade – the great price compared with seriously good reviews made it an easy buy!

I ordered it on Saturday and received it on Tuesday with free delivery (I don’t have Amazon Prime at the moment).

Great packaging – an ideal gift

Be sure to register online for an extended warranty

Accessories included too!

It includes two USB to microUSB cables (one short, the other long) for charging the powerbank.

It’s not as bulky as I expected

Three USB ports and a microUSB (for charging)

Looking at the tech specs, it can provide up to 2.4A power to each USB port. A regular USB charger would provide 1A of power, so it’s more than twice as fast to charge from the powerbank than a mains to USB plug.

Overall, a great device. It has a solid, robust feel to it, without being so bulky you can’t take it with you. I could easily carry it in side pocket of cargo trousers/shorts or throw it in my backpack.

On a side note, buying through Amazon takes away any risk of the item becoming defective – even if you’re out of any official warranty period, in my experience they’ll offer a replacement or refund, even if you’ve had the product for a few years.
